OPERATING

Efficiency

87%–89% .

Switching frequency

100kHz

Thermal protection

Yes

Programming

Analogue Programming of voltage and current by

0-5V.

Programming speed

See table

Master/Slave operation

Parallel and series operation with equal current

and voltage sharing. In this way two or more SM-

units can together be used as one high power unit.

Voltage and current of the units is controlled by the

master (by potentiometers or by programming).

Series operation up to 600V

Metering

Digital meters standard

Indicators

CV/CC mode, OVP triggered LEDs

MTBF

500,000hrs

BATTERY CHARGING

The CV/CC regulated power supplies are suitable for battery charging.

Ask for the special datasheet “BATTERY CHARGING WITH SM-series POWER

SUPPLIES”. This datasheet contains information about protective measures

against accidental battery reversing.
